http://issues.apache.org/bugzilla/show_bug.cgi?id=30085 ClassCastException using Oracle BLOB if Oracle JDBC jar is in both /common/lib and [webapp]/lib Summary: ClassCastException using Oracle BLOB if Oracle JDBC jar is in both /common/lib and [webapp]/lib Product: Tomcat 5 Version: 5.0.25 Platform: All OS/Version: All Status: NEW Severity: Normal Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Reproduceble on both Windows 2000 and Solaris. Use either classes12.zip (rename to classes12.jar) or ojdbc.jar from Oracle. Place either of the jar files into both /common/lib and [webapp]/lib, configure webapp to use org.apache.commons.dbcp.BasicDataSourceFactory in the context XML file. Get blob from Oracle database via ResultSet.getBlob() and cast it to a oracle.sql.BLOB. --> ClassCastException occures even though the blob in the ResultSet is an oracle.sql.BLOB, as indicated by debugger. Solution: remove the Oracle JDBC jar from [webapps]/lib directory and everything works fine. Seems to be an issue with Catalina's classloader. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
